The Thai coconut soup recipe that has been quietly circulating since the Department of International Trade Promotion shared it deserves more than a passing glance: it is, quite simply, one of the most restorative bowls you can put together on a weeknight. Lemongrass, ginger, lime and coconut milk in a single pot, ready in under half an hour. Winter has looked worse.
Why this Thai coconut soup recipe works so well
There is a particular discipline to a good Thai broth that lesser recipes miss: the aromatics must be cooked in fat first, briefly but properly, so that the ginger and lemongrass bloom before the liquid arrives. Here, a tablespoon of vegetable oil in a large pot over medium heat does exactly that. Two tablespoons each of grated fresh ginger and Blue Elephant red curry paste go in with one finely sliced stalk of lemongrass, stirred and cooked for one minute. The kitchen changes immediately.
Chicken stock follows gradually, 950ml of it, then three tablespoons of Tiparos fish sauce and a tablespoon of Thai palm sugar. The heat drops to low and the pot simmers for fifteen minutes, giving the broth time to deepen. Coconut milk, a full can of Pride, goes in next with 250g of shiitake mushrooms, halved if large. Another five minutes and the mushrooms are soft, their texture absorbing the richness around them.
The final assembly is quick: 450g of M&S cooked and frozen cold water prawns, two tablespoons of fresh lime juice, salt, and a handful of chopped coriander scattered over the top. Four nests of Mama instant rice vermicelli noodles swell in the bowl as you ladle the soup over them. The dish serves six, which means it is equally comfortable as a midweek supper and as something to put in front of guests who have arrived cold and unconvinced that January has anything to recommend it.
The ingredient logic, and where to find everything
Coconut milk earns its place in more ways than one. Beyond giving the broth its characteristic creaminess and body, it has anti-inflammatory properties that make this more than purely a comfort exercise. Lime juice brings vitamin C; the shiitake mushrooms add fibre; the ginger lends that familiar, slightly medicinal warmth that has made it a fixture in cold-weather cooking across South-East Asia for centuries. This is a soup that may just take the edge off the autumnal sniffles, though it would be worth making regardless.
Every ingredient in the recipe is available on Ocado, which matters on a weeknight when the prospect of hunting down fish sauce and palm sugar across multiple shops is the thing most likely to make you reach for a ready meal instead. The branded specifics here are not incidental: Blue Elephant’s red curry paste carries a particular depth, the Pride coconut milk is consistent in its fat content, and the Mama rice vermicelli noodles cook in minutes without turning to mush.
The recipe is also straightforwardly adaptable for a plant-based table. Replace the chicken stock with vegetable stock, swap the fish sauce for soy sauce or oyster sauce, leave out the prawns, and add pre-cooked tofu. The aromatics remain the same, and the soup loses none of its essential character. It is, in that sense, a good structural recipe: the technique is fixed, and the protein is almost beside the point.
Credit for the recipe and its accompanying image goes to the Department of International Trade Promotion, the Thai government body that has been placing this kind of good-faith culinary diplomacy in front of international audiences for years. The approach tends to work. You make the soup once, in November, and by December you are pricing up flights to M&S for the prawns has become a reflex and the lemongrass is always in the fridge. Some conversions are more gradual than others.
